What is the trick to remove the pins (#7) holding the coupler pins (#8) to the cylinder ? The D&A only says ‘remove’ them. Does not say how they are fixed. Are they press fit ? Punching them from either end does not move them.
Pics of both ends of a pin One end looks like it was ground flush after it was inserted. Punching it with a 5# sledge sounds like hitting an anvil. Solid. Cannot be remove the cylinder from the cavity until pins are removed. ??
